' 2 Claims. (Cl. 229-51 The present invention relates to that class ofcontainers embodying a rectangular cardboard primary container memberand'a wrapper which may be metal foil or com posite paper and foil.

The object of the invention is to provide a container of such characterwhich will have a fiat top when the package is filled and closed, andwhich will have a special form at the top so arranged that when thefolds of the outer wrap are released at the top of the package and movedupwardly, the package may be grasped and the top pressed inwardly'with'an action upon the cardboard inner body which projects its top upwardlyin gable formation. The projecting gable end may be grasped by theoperator and the entire top area, initially provided with a cut score orothertearirig line, will be torn away from the'underlying"body'fordispensing of contents of the bdoy for immediate use;

'After a desired removal of partial contents of the container, theprojected wrap portion may be folded into sealing relation with thecontents and in order to preserve the latter.

By means of the invention, a flat top rectangular container is providedwhich has all of the advantages of rewrap gable top containersheretofore proposed.

The invention will be described with reference to the accompanyingdrawings, in which:

Fig. 1 is a perspective view of an embodiment of the invention, showingthe outer wrap partially torn away;

Fig. 2 is a view in section showing the upper portion of the closedcontainer, the section being on the line 2-2, Fig. 3;

Fig. 3 is a plan view of the closed cardboard container body, with theencircling wrap in section;

Fig. 4 is a schematic view in vertical section showing the upper portionof the container ready for pressurecollapse of the cardboard innermember to project its upper end in gable formation convenient fortearing away the entire top of the package, and the cardboard top beingshown partly torn away by dotted lines;

Fig. 5 is a perspective view showing the form of the package after theouter wrap, which may be of foil or foil and paper, has been folded tore-seal the package;

Fig. 6 is an isometric View showing the torn-away top of the packagestill in its gable form after collapse thereof;

Fig. 7 is a plan view showing the blank from which the cardboardcontainer body is formed;

Fig. 8 is a sectional end view, reduced in size, the section being takenon the line 8-8, Fig. 4; and

Fig. 9 is a reduced sectional elevation taken generally on the line 99,Fig. 5.

Referring to Fig. 7 of the drawings, it will be seen that the blanktherein shown is that of a cardboard body, and consists of the majorface panels 1, 1x, the narrower side panels 2, 2x, and the lateralsealing lip 3. At the base of the blank merging into panel 1 is a bottomwall member 4 having locking tabs 5 adapted to be projected into slotsformed by the U cuts 6 in a corresponding wall member 2,750,101 PatentedJune 12, 1956 7 carried by the face panel 1x. Merging into each narrowerside panel 2 is a bottom closure flap 8.

Each side panel 2, 2x is provided with a top closure flap 9 adapted tounderlie top closure members 10, 10x.

Extending completely across the cardboard body blank is a weakened lineat 11, which may be provided by spaced cuts so that the area above thecuts may be torn away. Below tear line 11 are two spaced weakened lines12 and 13, the purpose of which will be hereinafter described. On eachside panel 2, 2x above line 13 (when the blank is formed up) are twoscore lines at 14 which lines merge and meet score lines 12 at theirtops. The apex of the meeting score lines 14 on each side panel 2, 2xmeets a score line 15 extending transversely of the blank andintersecting score lines 16 which are identical with those 7 In formingup the blank into a cardboard container body, lip3 is glued to sidepanel 2x under the same and the rectangular body thus provides closingthe bottom wall by first folding in the flaps 8, then flap 7, andfinally by inserting the tabs 5 in the U cuts 6, which completes the I-th n bein'g'as shown in Figs. 2 and 3.

bottom closing operation. The cardboard body member is then ready forfilling or may be initially provided with an outer wrap 17, and thelatter may be of foil, although preferably of foil and paper. Thus theinner face of the foil may carry a heat sealing medium.

After the cardboard container body is filled with material, theflaps 9are folded inward, followed by the flap 10 and finally by the fiap 10xwhich will be sealed down by glue or any suitable sealing material, theclosure The outer-wrap 17 may consist of foil with an inner layer orporous tissue, and heat sealing wax being disposed between the twosheets. Thus when the top of the wrap is folded down upon the top of thecardboard container, the folds of the wrap may be sealed by heat andpressure. At the same time the wax, although affording an excellentimpermeable seal, still would enable the folds at the top of the wrap tobe pulled apart so that these folds may be raised to the position atFigs. 1, 4 and 8.

When it is desired to open the package, the outer wrap having beenraised at its top, it is only necessary for the user to simultaneouslypress the major face walls 1 and 1x toward each other and at the sametime to press the side walls together, both of these pressures being atthe top of the cardboard body. By this action, the top areas of thenarrower side walls 2, 2x collapse on the vertical lines 15, and thepeaked area of each flap 9 is projected inwardly on the fold lines 16which act as hinged lines, causing that area at the top covered bymembers 10, 10x to rise as a gable member to the position of Fig. 4,Fig. 6 showing the resulting formation.

Reference to Fig. 4 will show that the gable formation of the coardboardbody top and its projection upwardly enables the user to grasp the toparea and tear it away on the tear lines 11. The foil or foil and paperwrap may be folded, as shown in Fig. 5, after the contents of thecontainer have been partially removed for use. Thus, as shown in Figs. 5and 8, the wrap 17 may be folded inwardly at the narrow sides of thecontainer and then rolled down in the manner indicated at 172:.

After the normally flat and rectangular top area of the cardboardcontainer has been torn away, the container walls, due to the provisionof the lines of collapse at 14, 15 and 12, may be brought together intogable formation, as shown in Fig. 9, and the rolled over outer wrap willmaintain the sealing abutment of the cardboard top layers. As thecontainer is repeatedly used in gradually dispensing the contents, itmay be re-sealed in the manner described until the contents areexhausted.

It will be understood that, if desired, one of the closure flaps 9-maybedispensed with and that in such case generally. the. opposite.finp.,9..will .bemade .longerutoxextends across the top of the bodymember. It is preferred, however, that two flaps 9 be employed.
